\VILLIAM A. LOCKE, OF PROVIDENCE, RHODE ISLAND.

COLLAR-BUTTON.

SPECIFICATION forming part of Letters Patent'No. 645,298, dated March 13, 1900.

Application filed January 26, 1900. Serial No- 2,869. (No model.)

1'0 to whom it may concern:

Be it known that 1, WILLIAM A. LOCKE, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Collar-Buttons, of which the following is a specification.

This invention has reference to an improvement in sheet-metal collar-buttons, and it consists in the peculiar and novel construction more fully set forth hereinafter.

In collar-buttons drawn up from sheet metal the shoe and shank were provided with a button usually secured to the end of the shank by solder. The use of solder in drawn or stamped sheet-metal goods is very objectionable, as the heat used in soldering draws out the stifiness and resiliency of the metal.

The object of this invention is to fasten the button to the end of the shank more securely and durably without the use of solder.

Figure 1 is a side view of the shoe and the shank, showing the end of the shank split.

Fig. 2 is a side view of the shoe and shank,-

showing the split end of the shank swaged out to form a dovetail. Fig. 3 is an end view of the shoe and shank. Fig. 4. illustrates in perspective the parts which when combined form my improved collar-button. Fig. 5 is a sectional view of the dies, showing the dies and the parts shown in Fig. 4 in the relative position when being secured together. Fig. 6 is a sectional view showing the parts secured-together. Fig. 7 is a side view of the completed button.

In the drawings, a indicates the shoe; b, the shank; b, the split ends of the shank, forming the dovetail connection; 0, a plug of soft metalsuch as lead, tin, or similar metal-and d a member which supports the button. When a spherical or approximatelysphericalbu tton is to be secured to the shank, the member cl is of the shape of a ball, and preferably a hollow ball, as is shown in Figs. 5 and 6. e is a cover for the button, which is cup-shaped, so that it may be compressed onto the stem above the dovetail formed of the split end of the shank, and ffdies made to inclose the shoe and the shank of the button. They have the concave portion f at the lower end and the space f in their upper portion. g is the lower die in which the concavity g is formed to correspond to the shape of the button desired to be secured.

In constructing the button the shoe a and shank b are formed in suitable dies in the usual way. The end of the shank is now split, and the split ends 17' b are spread out to form the dovetail end, as shown in the drawings. The so-prepared shoe and shank are now placed into the dies f f, with the shoe in the position shown in Fig. 5. Into the concavity g of the die g is now placed the cover e, and into the cover 6 the member cl, and on the member of the plug a, of soft metal. When now the die g is forced against the dies ff, the upper edges of the cup-shaped'cover e are forced inward toward the shank by the concave portion f of the dies f f, while at the same time all the parts are pushed upward until the shoe a bears against the upper surface of the opening or space f in the dies ff, as is shown in Fig. 6. The soft-metal plug 6 is now compressed and spreads out to fill all the spaces into which the soft metal can flow under pressure, and when the dies meet the button is firmly secured to the shank, as is shown in Fig. 6.

The completed button has all the strength, finish, and resilience secured by forming the parts in dies and is stronger, more durable, and of better finish than a soldered button can be made to be.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a collar or similar button, the combination with the shoe and the split end of the shank, of a plug of soft metal, a member having the form of the interior of the buttonhead, and a button-cover secured by closing the edge of the same around the shank and interior member and compressing the softmetal plug, as described.

2. A button having a shoe and a shank formed in one piece, the end of the shank formed into dovetails, and a button-head consisting of the button-cover, a member in the cover, and soft metal in and between the adjacent parts, as described.
